EYELET-SETTING MACHINE.

Application filed January 25, 1910.

To all fwhom it may concern:

Be it known that I, WILLIAM HUGHES, a citizen of the United States, residing at Taunton, in the county of Bristol, State of Massachusetts, have invented a certain new and useful Improvement in EyeletSetting Machines, of which the following is a specication, reference being had therein to the accompanying drawings.

In machines for setting eyelets there is usually provided a raceway through which the eyelets are fed into position to be picked off by a spindle connected with said mechanism, said spindle having a vertically re ciprocable movement through a hollow fixed cylinder, termed the under set, the upper end of said cylinder forming an anvil upon which the flange of the eyelet rests when the spindle moves downward after having picked the eyelet from the raceway and there is also provided a vertically reciprocable plunger, termed the top set, which moves down as said spindle moves down and engages in the barrel of the eyelet after the eyelet has been inserted in the work, the work being fed on a work plate through which the spindle reciprocates. Heretofore the spindle used has been circular in crosssection and the perforation through the hollow under set through which the plunger reciprocates has been circular in cross-section. When the eyelets pass down through the raceway, means are usually provided whereby they will all be fed in an upright position so that the spindle can easily pick them from the raceway but although they ride down the raceway on end, there is nothing to prevent them from turning or rotating on their axes. When the eyelets which are employed are formed with a tubular barrel, circular in cross-section, it does not matter if the eyelets do turn on their axes as long as they are retained on end and it does not matter if they should rotate on the spindle after the spindle has picked them from the raceway because they are alike on all sides. But when eyelets are used having a barrel which is rectangular in cross-section or otherwise non-circular it is important when the eyelets are to be set in a row, as for instance, when they are being set in the upper of a shoe, that the corresponding sides of the barrel should lie in the same direction, that is, if the barrel is square, one of the straight sides of the inner periphery should Specification of Letters Patent.

Serial No. 539,969. s ia lie parallel with the edge of the opening in the shoe. Or if it be desired to set the eyelets in such manner that the straight edge of the inner periphery shall be at an angle to the edge of the opening in the shoe, then all of the eyelets in the series should be set at the same angle. lVhen the spindle is circular in cross-section as hereto-fore used, an eyelet even with a square opening can rotate thereon, so that although the spindle may successfully pick the eyelets from the raceway, yet there is no certainty at all that the eyelets will be properly alined with each other so as to make sure that the straight edges will be in proper line.

The object of the present invent-ion is to so construct the mechanism that when eyelets are employed whose eyes are non-circular in cross-section whatever may be their position on their axes when picked from the raceway by the spindle they will be properly centered and alined before they are set.

The invention consists substantially in having the plunger or spindle and the follower or upper set both formed with a noncircular cross-section corresponding with the non-circular cross-sectional contour of the inner periphery of the eyelet and having the hollow cylinder or under set through which the plunger or spindle reciprocates formed with the upper portion at least of its bore of a similar non-circular cross-section.

The invention will be fully understood from the following description taken in connection with the accompanying drawings, and the novel features will be pointed out and clearly deiined in the claims at the close of the specilication.

In the drawings,-Figure l is a side elevation partly in section of the upper and under sets of an eyelet setting machine and the mounts for the sets embodying the invention showing the parts with the upper set or follower raised and with an eyelet resting upon the under setor cylinder and a spindle extending up through the cylinder as will be the case after the eyelet has been picked from the raceway. Fig. 2 is a similar view to Fig. 1 showing the parts in the position after the upper set or follower has descended to set the eyelet and the spindle has descended out of the way. Fig. 3 is a section on line 3 3 of Fig. l looking upward. Fig. 4 is a section o-n line 4 4 of Fig. l looking downward. Fig. 5l is a section on line ot F 1 looking downward. Fig. 6 is a perspective view enlarged ot one ot the eyelets.

Referring now to the drawings The spindle A is 'formed with a cylindrical lower portion. 10 and an upper portion 11 formed square in cross-section tapering upward, said spindle being vertically slidable in the hollow under set B which serves as a bearing as well as an anvil for the eyelet. The cylindrical lower portion l0 ot the spindle has a close sliding tit in the cylindrical interior bore of the cylindrical under set B. The greatest diameter of the square portion 11 is no greater' than the diameter ot' the cylindrical portion 10. The lower portion 23 of the under set B is made of reduced eX- tcrior diameter forming a shank which is fitted into the upper end of the cylindrical tubular mount C, the diminished diameter of the cylinder which forms the shank portion 23 resulting in the formation ot a shoulder 12 which rests on the upper end of the mount C. A set screw 13 passing through the side ot the mount C securely binds the tubular under set B to the mount C.

rl`he lower end ot the spindle A is formed with a head 14 which is seated. upon a spring 15, said spring being seated upon the bottom 16 or the tubular mount C. The head 14Y is slidable within the tubular interior of the mount C and is normally held by the spring 15 with a yielding pressure against the lower end of the tubular under set B, forming a stop which limits the upward movement of the spindle. Vhen pressure is broughtl upon the upper end of the spindle A, the spindle will be depressed, thereby contracting the spring 15. Vlfhen the downward pressure upon the spindle is released the spring 15 will carry the spindle up again until the head 14- strikes the lower end of the under set B. By loosening the set screw 13, the cylindrical under set B may be turned in its bearing in the cylinder C and adjusted to any position on its axis. The upper portion of the interior bore of the under set B, for instance as shown in the drawings the portion above the shoulder 17, is made square in crosssection corresponding with the largest cross-section of the square portion 11 of the spindle so that the spindle can slide in the hollow under set but not turn therein until the spindle is moved down to a point where the greatest diameter of the square portion of the spindle is less than the smallest diameter ot the bore at that point. The largest square section of the spindle is small enough to be inclosed in a circle corresponding with the circular cross-section of the cylindrical portion of the spindle. By loosening the screw 13 as previously described, the spindle may be set to turn its square sides to adjust it as desired.

The square portion 1l ot the spindle is formed with an upwardly diminishing diameter and terminates in a pointed portion 1.8. their the eyelet as 19, is picked from the raceway by the spindle the pointed upper end ot the spindle will enter the barrel ot the eyelet. The upper part oi the square portion of the spindle will be smaller in diameter than the interior diameter of the eyelet and whatever may be the position of the eyelet on its axis when it is lirst picked from the raceway by the pointed end of the barrel, the eyelet will swing around as it slides down over the spindle until its square edges are parallel with the square edges of the spindle, so that every eyelet, no matter what position on its axis it occupies when it is picked from the raceway will be centered by the spindle before the plunger descends.

The plunger' or follower D is formed with a tapering lower end 20, square in cross-section as shown in Fig. 3 and is formed with a cylindrical shank 21 which is adjustably mounted in a tubular head E and secured therein by a set screw 22, said plunger being adjustable on its axis so that the tlat taces of the square lower portion 2() may be adjusted to correspond with the square faces of the spindle A so that after the eyelet has been picked oil by the spindle and properly centered upon the upper end of the under set B the lower end of the plunger will be properly alined with the square eye of the eyelet.
